In wireless communication networks using carrier aggregation including a secondary component carrier in unlicensed spectrum, a user equipment (UE) may monitor a downlink radio link quality of secondary cells for an event indicating failure of a communication link in the unlicensed spectrum with a secondary cell. The UE detects one or more failure events based on the downlink radio link quality. When a designated set of failure events is detected, the UE declares a failure state on the secondary cell. In response to the failure state, the UE may adjust operations related to the secondary component carrier in the unlicensed spectrum in order to save power and resources.

Managing secondary cell connections in unlicensed spectrum

A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives a request to receive a Multimedia Broadcast Multicast Service (MBMS) service associated with a service area identity (SAI) and a second frequency. The apparatus performs inter-frequency cell reselection from a first cell transmitting at a first frequency to a second cell transmitting at the second frequency, the second cell being an inter-frequency neighbor cell to the first cell. The apparatus receives system information from the second cell. The apparatus determines that the second cell transmitting at the second frequency is unassociated with the SAI based on the received system information. The apparatus blacklists the SAI on the second frequency in a blacklist for at least a period of time upon determining that the second cell is unassociated with the SAI.

Method of enhancing user experience by using system information in LTE EMBMS

Disclosed are methods and apparatus for performing a better PLMN (BPLMN) search during connected mode DRX. In one aspect, a user equipment (UE) detects a trigger to begin a BPLMN search while in connected mode discontinuous reception (CDRX); determines whether it is configured for a manual BPLMN search; determine whether the CDRX duration is greater than or equal to the minimum amount of time required to perform the manual BPLMN search; and when determined that the CDRX duration is greater than or equal to the minimum amount of time required for the BPLMN search, performs the manual BPLMN search while in the CDRX.
